Make Fresh Water From Sea Water
The AN65 Watermaker Makes 65 Litres of Fresh Water Per Hour From Sea Water Where & When You Need It!
Why You Should Choose An Aqua Nautica Watermaker
- Operates on a 12V power supply so you don’t need a generator and there is no vibration!
- Utilises an Aqua Nautica Clark Energy Recovery Pump to boost water pressure to 800PSI!
- Uses 85% less energy consumption then conventional hi-pressure Watermakers!
- Quiet operation. Less than 64db @ 1m!
- Simple installation with very little maintenance!
- Simple to operate and you don’t need to adjust pressures!
- Entirely hydraulically operated!
- The water is automatically self-regulating according to operating conditions
What Is A Clark Energy Recover Pump?
Clark Pumps allows seawater to pressurised to 800PSI (55 BAR) with much less energy than a conventional reverse osmosis system.
The Aqua Nautica AN65 Clark Energy Recovery Pump is manufactured in house using CNC technology and quality machined and non machined materials and components.
The energy recovery pump and smaller recovery valve both have opposing cylinders and two pistons connected by a common rail. The system is completely hydraulically operated so valves open and shut automatically. Water pressure from the 12V feed pump is diverted to the outside of the piston in each cylinder pushing the piston one way or the other. The waste brine stream from the membrane provides a power assist function and feeds through a recovery valve and is directed to the opposing side of the piston forcing the piston in the opposite direction.
The sea water feed pressure to the membrane is boosted to 800 PSI (55 BAR) before it is squeezed through the reverse osmosis membrane making potable water.
How Much Sea Water Does It Take To Make 1 Litre Of Potable Water
- When seawater is pressurised through a membrane, only 10% passes through the membrane walls as pure water.
- You need 10 litres of pressurised water to make 1 litre of pure water!
What Is The Approximate PPM of The Water Produced
- The average TDS (Totally Dissolved Solids) of sea water is 35,000ppm (Parts Per Million)
- The freshwater produced from the Aqua Nautica AN30 watermaker will have a TDS of less than 500ppm.
